One Chick-Fil-A Menu Item Will Help Upgrade Your Cookies & Cream Shake

Chick-fil-A may not have an official secret menu, as confirmed by the chain's website, but fans are well aware that there are a number of Chick-fil-A hacks they can use to make their order even more exciting, spicier, or cheaper. Ordering in person or using the chain's app, you can tweak regular Chick-fil-A menu items and come up with custom dishes to eat, from chicken taco burgers to a frosted Arnold Palmer lemonade.

Some Chick-fil-A "secrets" vary by location, with guacamole packets and "special cheese sauce" doled out at select restaurants. If you're in Arizona or Texas, for example, you can order a side of jalapeños, while chicken gravy is available in Missouri, West Virginia, and Kentucky. Although employees are not permitted to prepare any unofficial dishes, customers still have a lot of freedom to hack completely new menu items by reconfiguring these ingredients at the table. For dessert lovers, one DIY trick makes Chick-fil-A's milkshakes even more decadent.

A double cookie milkshake for $1.55 extra

When a sugar craving strikes, you can upgrade your Chick-fil-A cookies and cream shake to something called a double cookie milkshake. All you need to do is purchase the cookies and cream shake and cough up an additional $1.55 for a chocolate chunk cookie. From there, just crumble the cookie into the milkshake, mix, and "grab a straw and a spoon — you'll want every last sip/bite of this cookielicious concoction," as Morgan Crego writes for Chick-fil-A. TikTok user Anna Woosley agrees; she made a PSA to fellow Chick-fil-A fans that she had gotten the double cookie shake three times in one week and that if you try it, "your life is never gonna be the same."

This isn't the only way to upgrade a shake from the chain. One game-changing Chick-fil-A shake hack takes advantage of the chain's chocolate fudge brownies, which can be crumbled up and sipped through a straw with your ice cream. Redditors are also fans of requesting staff members to blend Oreos into their chocolate, strawberry, and other milkshake flavors.
